WATER-CLOSET.

SPECIFICATION forming part of Letters Patent No. 616,843, dated December2'7, 188. Application filed October 3, 1896, Serial No. 607,813. (Nomodel.)

To (tZZ whont it may concern.-

Be it known that I, DANIEL HURST, a sub-- ject of the Queen of GreatBritain and Ireland, and a resident of 11 Gilda Brook road, Eccles,county of Lancaster, England, have invented certain Improvements inWater- Olosets, of which the following is aspecification.

My said invention has for its object improvements in or applicable towater-closets.

The first part of my said invention relates to the means for controllingthe flow of water from the main supply to the flushing cylinder orcistern and thence to the closet-pan.

In order that my said invention may be more clearly set forth, I willdescribe the same with reference to the accompanying drawings.

Figure 1 is a front elevation of a watercloset constructed in accordancewith my said invention, in which A is the closet-pan, k is the seat, andBis the valve-box which controls the supply of water from the water-mainf to the flushing-cistern P. The ventilating or fume shaft w iscontinued to any convenient outlet from the building. Fig. 2 is asectional elevation of the valve-box B and its connections.

Before proceeding to the details of the parts I will give a generaldescription, with reference more particularly to Fig. 1. When a personsits on the seat 70, the latter oscillates so as to raise thevalve-spindle d, whereby water is allowed to pass from the main f to theflushing-cistern P. On the weight of the person being removed thevalve-spindle (1 falls and thereby shuts off the water from the main andat the same time permits the water to descend from the flushing-cisternP to the closet-pan. Such a circulation is, however, well known at thepresent time and of itself forms no part of my said invention, whichrelates to improvements in the details of such closets whereby they aremade much more efficient.

Referring now to Fig. 2, any weight on the fore part of the seat willcause the rear part to lift. On rising the rear part of the seat willpress against the cross-head h of the On the valve-spindle drisvalve-spindle (1.

ing the lower valve a will be lifted against the lower seating a andwill prevent access of water to the flushing-pipe n, which leads to thecloset-pan and is connected therewith in the usual manner. Thevalve-spindle d is hollowed to receive the stalk c of the upper valve tosuch a depth that it may rise so far as to nearly touch the seating abefore lifting the valve-stalk c. On the stalk c be-, ing lifted theupper valve or rises and permits water to flow from the water-main f tothe branch 6, leading to the flushing-cistern P, Fig. 1. Yhen the weightof the person is taken away, the valve-spindle (1 falls and opens thevalve a, being aided by the weight .9. On this happening the pressure ofthe water-supply in the main closes the upper valve a. now descendsalong the branch 6, through the lower valve, and thence along the branch*0 to the closet-pan.

The stalk or spindle c of the upper valve is screwed into the valve a,and by this means the distance apart or the lift of the upper valve a inproportion to that of the lower valve may be regulated to suit theconditions of the water-pressure in any particular case. The valves arefaced with rubber, leather, or other suitable material for such purpose.

I prefer to make the facing m of the valve a of india-rubber ofconsiderable thickness and to form a somewhat deep rim on thevalveseating (L The object of this is that when the pressure of thewater in the flushing-cistern P reaches a certain point the. valve awill be thereby depressed to such an extent as will allow the uppervalve or to descend under the pressure of the main supply and thus toclose the valve'a and cut off the water from the main. The thick rubberand deep rim enable this action to take place without permitting theescape of flushing-water through the lower valve.

On the spindle d, under the lower valve a, a collar (1, 0f india-rubberor other elastic material is used to act as a buffer on the descent ofthe lower valve, so as to minimize the shock. Similar elastic buffersare provided at j on the ends of the cross-head h where it comes intocontact with the seat. The cross The Water in the flushing-cylinder vhead is screwed on the spindle cl, so that its position may be varied tosuit seats of different heights. 7

What I claim as my invention and desire to secure by Letters Patent, is

The valve a provided with a thick facing of rubber and having itsspindle hollowed at the upper end, in combination with the valveseat orprovided with a deep rim opposite the said facing, the valve a having astem which enters this hollow of the other valve-spindle, the valve aclosing the discharge into the pan just before causing the valve to toopen the supply of the cistern, the thick rubber and deep rim allowingthe action Without the I 5 escape of flushing-Water through the lowervalve substantially as set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

DANIEL HURST.
